Multi-split air conditioning in Finchley

Twin and triple systems suit Finchley homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.

Multi-split is a good fit for Finchley flats and maisonettes where only a balcony or one rear wall is available. We cover Finchley as part of London, roughly 8 miles from central London. Homes in N3 are all within our coverage.

Prices in Finchley

For Finchley, expect roughly £3,245 to £10,245 for 2–4 rooms, VAT included, adjusted for typical London rates. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. What moves a quote in Finchley up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. As an example, the Triple option (three rooms with mixed indoor styles and Wi-Fi control throughout) would typically be £4,395–£7,195 here.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.

Planning and permissions

Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.

The survey

We book surveys in Finchley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Finchley cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
